Other points of interest[edit]


  1. Open the red door in the middle of the map and head south, towards armor bonuses. Quickly run west into the room here and pick up a rocket and a medikit. (sector 191)
  2. In the southeast area with the berserk pack over the nukage, head into the nukage tunnel behind the berserk pack and find an obstacle blocking a switch. Blow it up, flip the switch, then head west of where the berserk pack is to a box of rockets. Open the north wall here to find containers and a medikit. (sector 263)
  3. In the area west of the center of the map, get to the middle structure and flip the switch to lower several walls, including two to the northwest. Before jumping to those ledges, blow up the obstacle to the northwest there as well as the destructible column to the north. Now jump there and enter the small section of nukage where a switch is. Run northeast and north through the nukage to get energy cells, a stimpack, and a medikit. (sector 420)
  4. At the east side, go to the chaingun at the west side of the room and open the north wall to get a computer area map. (sector 490)
